Instructions
Set the Instant Pot to Sauté mode. Add olive oil and let it heat up.
Add sliced beef sirloin to the pot in batches, browning each side for about 2-3 minutes. Remove the beef and set it aside.
In the same pot, add chopped onion and garlic, cooking until softened (about 2-3 minutes).
Stir in the sliced mushrooms and continue cooking until they release their juices and are tender (about 3-4 minutes).
Add beef broth, Worcestershire sauce, Dijon mustard, dried thyme, and the browned beef back into the pot. Season with salt and pepper.
Close the lid of the Instant Pot, set it to Manual mode, and cook on high pressure for 10 minutes.
Once the time is up, carefully perform a quick release of the pressure.
After releasing the pressure, stir in the sour cream and the cornstarch-water mixture. Set the pot to Sauté mode again and cook for an additional 2-3 minutes until the sauce thickens.
Meanwhile, cook the egg noodles separately according to package instructions. Drain and set aside.
Serve the beef stroganoff sauce over the cooked egg noodles and garnish with fresh parsley.
